The title says it all, my "source" over in Italy sent me this photo.

(I dunno, the 315 looks more towards aqua than sage green, that's what he said to me)

One of these 315s is on its way to me from Italy.

Both are 15 KV rated. The 6315 is CD 376.2, and the M 315 CA is CD 376.

The 6315 is three parts, and the M 315 CA is also three parts. (thanks to Nora Coppo for correcting my original mis-cue).

If I ever get over this "mutant martian death flu" that has been going around around and around again, then maybe my head and mind will clear up....

M stands for Medium Voltage, 3 (for three parts), 15 for 15KV, and CA is the wider cable grooves and saddle groove to accomodate aluminum power cables.
